The Zeppelin group

The industry sector of the Zeppelin group is among the leading

manufacturers of plants for the storage, conveying, blending,

and proportioning of high-quality bulk solids. Thanks to our

world-wide activities and locations in all important industrial

centres we can always provide our clients with the latest, most

innovative and secure process technology – to ensure maximum

economic success.

As the direct successor of Earl Ferdinand von Zeppelin who,

more than 100 years ago, turned the human dream of flying into

reality by building his legendary air ships we are used to looking

ahead. Constantly innovating, striving for perfection and maximum

functionality in our products has turned us into the company

that Zeppelin is known as today: the technological leader for

handling high-quality bulk solids.

100 years of meeting your tasks has helped us gain strength – through experience.

On site world-wide – always near our customers. Production plants in Germany, Belgium, Brazil, and China as well as partners and representations all over the world enable Zeppelin to serve our customers with speed, flexibility and the utmost closeness to our customers. More than 200 engineers – including specialists in chemical engineering – guarantee innovative and economic design of plants.

The industrial Zeppelin group and the number of divisions belong-

ing to it orient themselves strictly to the requirements of their

different groups of clients – all activities have, however, one thing

in common: the economic handling of high-quality bulk solids.

Silo plants for the plastic, food, and chemical industry integrated in

the general logistics concept – starting with consultation and design

up to manufacture, assembly, and after-sales service.

Turn-key plants for the plastics processing and chemical industry

as well as for rubber producers and tiremakers.

Conveying components for any application: for powders or pellets,

for high or low pressures, for products with good or poor flowability,

for standard or special applications.

Silogistic: turn-key plants for plastics producers, engineering com-

panies, and forwarders from the world-wide leader in the planning

and construction of logistic centers and manufacturing plants.

Competence in bulk solids handling – you can rely on Zeppelin.

As far as construction of silos is concerned Zeppelin has been the leader in the international market for decades. Thanks to our own modern manu-facturing plant and the international experience of our assembly staff and service engineers we guarantee quality of the highest level.

Pulling all the strings: the central office for the industry sector is located in Friedrichshafen, Germany. Here, in the largest Test Center in the world for pellets and powders tests are carried out on an industrial scale – the results of which are available to the subsidiaries. On this basis our clients are always on the safe side – no matter where their plant is located.

Ultrasonic level indicator:For touch-free and continuous control of filling levels, suitable for granular bulk solids and those giving-off dust.

Filling level control and visualization

Visualization:Always everything under control: All relevant information concerning your silos can be recovered from modern software.

Silot (electromechanical plumbline gauge):For virtually continuous control of the filling level, suitable for granular up to highly dust evolving bulk solids. A starting impulse lowers the measuring cable with the contact weight by means of a cable winch in the silo.

Rotary paddle type limit switch:For use as maximum level indicator (assembly in the silo roof) or for indication of minimum or inter-mediate filling levels (assembly in the silo shell or silo cone). Housing made from die-cast aluminium, measuring blade and blade shaft made from stainless steel, protec-tive tube made from aluminium. Optionally an explosion-proof type is also available.

Vibration limit switch:For use as maximum level indicator (assembly in the silo roof) or for indication of intermediate or minimum filling level (assembly in the silo shell or the cone). Housing made from die-cast aluminium, extension arm made from stainless steel. Optionally an explosion-proof type is available.

Load cell:Reliable and simple possibility for continuous weighing of a complete silo. Independent from the type of bulk solids (powder or pellets) the silo contents will be recorded by load cells.

Companies who do their sums opt for quality right

from the start – because investments have to pay

from themselves also at long-term.

In other words: The better the system design, the more

professional the logistics concept, and the higher the

fabrication quality the more economic the silo system –

and the better your profits! In short: the sooner you

get in touch with Zeppelin, the better!

Zeppelin long-term quality means money well spent.

Manufacturing competence

Patented technology, e. g. special machines for cone-forming means a competitive advantage for us – and first-class products for you. Innovative welding techniques (such as simultaneous double-sided welding) speed up the fabrication of your product, and guarantee a minimum of weld seams in lasting Zeppelin quality.

Zeppelin uses only high-calibre professionals for its production, too. Our TÜV-certified welders undergo extensive in-house training in the interests of long-term product quality. From your point of view this means an optimum surface finish for your silo, resulting in optimum flow properties and maximum strength.

Water torch: Fast – precise – powerful. The water torch cuts aluminium plates up to approx. 200 mm and steel plates up to approx. 150 mm with a pump pressure of 4100 bar.

It goes without saying that quality proce-

dures at Zeppelin are everything you would

expect from such a first-class supplier.

This is not only for your benefit but also for

the entire industry: for example, it was our

engineers who assisted the TÜV authorities

in defining the DIN calculation regulations.

With Zeppelin you will get the future under control

Quality management

Vertical assembly of Zeppelin silos: a further guarantee for extreme precision and hence maximum sta-bility. In the long term, this means satisfied and successful customers.

As an internationally active and successful industrial group Zeppelin has all important and relevant approvals for welding and manufacturing techniques.

All quality tests (whether destruc-tive or non-destructive) are carried out in the Zeppelin laboratories.
